| Abstract |
The macrobenthic fauna of all types of intertidal area of the Surinam coast, mainly mud flats, were briefly studied by coring. Crustaceans dominated; polychaetes and molluscs were poorly represented. The highest biomass values (32 to 37 g.m-2 ADW, mainly contributed by Uca maracoani) were found around high tide level, at the border of the mangrove forest. Just outside the Uca zone, on sheltered places also high values (ca 20g.m-2 ADW, mainly contributed by Tanaidacea) were found. In the middle and lower parts of the flats biomass was low (only a few g.m-2 or less), probably a result of the instability of the sediment. The following crustaceans not recorded previously for Surinam were found living in the intertidal clay and mud: Hexapanopeus schmitti, Cycloplax pinnotheroides, Pinnixa sayana (Brachyura), and Upogebia brasiliensis (Macrura). |
